MACHINE FOR SAWING LASTS.

, Application filed July 26, 1920. Serial No. 398,935.

To all wiwmit may concern Be it known that I, Tnsononn \VALTnn McNrcnoL,a citizen of the United States t America, and a resident of Swampscott,in

the county of Essex and Commonwealth of lviassachusetts, have inventedcertain new.

and useful Improvements in Machines for Sawing Lasts, of which thefollowing is a specification.

This invention relates to machines for ticular object of the presentinvention is to provide an attachment for circular saw machines by whicha V-shaped notch may be cut in the toe end of a last preparatory to thereshaping of the last to conform to modern styles.

The invention consists in slid-ably mounting on a sawing machine a framehaving pivoted thereto a work-supporting member provided with means forlimiting its movement in either direction about its pivot. The inventionconsists further in providing said pivoted member with a plurality of adustable devices for supporting the last or ot er work whereby said 'workmay be BOSliLlOIlQCl on said member at any desired angle and inclinationrelatively thereto.

The invention consists also in certain novel features of constructionand arrangement of parts which will be understood readily by referenceto the descripgtion of the drawings and to the claims to e hereinaitergiven. I

For the purpose of illustrating the invention, one preferred form isillustrated in the drawings, this form havin beenfound to givesatisfactory and relizihle results, although it is to be understood thatthe various instrumentalities of which the invention consists can bevariously arranged and organized, and that the invention is not limitedto the recise arrangement and organization of t e instrumentalities as.herein shown and described except as required by the scope of theappended claims.

()f the drawings:

Figure 1 represents a perspective view of an apparatus embodying'theprinciples of the present invention, the same being shown mounted upon acircular sawingmachine of usual construction.

Figure 2 represents a longitudinal section of the same, showing inelevation the back of'the pivoted work-supporting member and the meansfor actuating the adjustable devices for positioning said work upon'said member.

Figure 3 represents a section on line 3, 3, on Fig. 2.

Figure 4 represents a vertical section on line 4, 4, on Fig. 2 showingthe work-supporting member in its rearmost position.

Figure 5 represents an elevation of the device showing'thework-supporting member in its forward position.

Figure (3 represents an elevation. of a last to be operated upon.

Figure 7 represents an elevation of the same after the first out hasbeen made therein, and

Figure 8 represents an elevation of the same after the second and finalout has been made therein.

Similar characters indicate like arts throughout the several figures ofthe (iiawings. v

in the drawings, 10 is the top of a sawing machine provided with arevoluble circular saw 11, said machine being of any well-knownconstruction.

This top 10 is provided with rooves 12 parallel. with the side faces oft e saw 11 and on opposite sides thereof.

Into these grooves 12 project guide ribs 13 or similar members securedto the under side of a reciprocatory frame 14.

On the frame 14. are secured brackets 15 and 16 provided with alinedbearings for the trunnions 17 formed upon plates 18 secured to theopposite ends of a tilting member 19 having an upwardly extending handle20.

The lower centralportion oi the member 19 is cut away as indicated at 21thereby forming a depression, lengthwise of whicextends a rod 22 theends of which project through the downwardly extending ears 23 of themember 19 and the plates 18 andhave positioning nuts 24: threaded to theprojecting portions thereof.

In front of said rod 22 is a revoluble shaft 25 havingright andleft handthreads 26 extending through fingers 27, the forward ends of which areprovided with pointedpins 28 adapted to engage the work 29 to be sawed.

In the drawingsthis work. is shown as a last as represented in elevationin Fig. 6. The rear ends of the fingers 27 are provided with alinedcylin rical openings through which the rod 22 extends.

One end of said shaft 25 is provided with.

a hand wheel 31 by which said shaft may be rotated to move the fingers27 toward and from each other.

The front face of the member 19 has also secured thereto, the angleirons 32 having a plurality of openings 33, either of which is adaptedto receive the threaded projection 34 extending forwardly from themember 19 and provided with the clamping nut 35 This constructionprovides a means whereby the angle irons 32 may be adjusted toward andfrom each other.

The outwardly extending parallel ears of said-angle irons 32 are alsoprovided with a plurality of threaded holes 36 in either of which isadapted to be mounted a revoluble threaded pin 37 the inner end of whichis preferably pointed and adapted to engage with the sides of the last29 or other work to be operated upon.

To the front face of the member 19 is also secured a. plate 38 the lowerend of which is inclined downwardly and rearwardlyas indicated at 40.

The plate 38 has a plurality of threaded openings 39 therein either ofwhich is adapted to receive the revoluble positioning bolt 41 extendingthrough the member 19 and provided at its rear end with turning meansThe upper hole 39 is used for long lasts and the lowerhole 39 for shortlasts, the purpose of said bolt being to retain the last 29 or otherwork at the desired inclination to the front face of the member 19.the'front end of'the bolt 41 bearing against the rear face of the lastand being adplsted until the proper inclination is attained.

The inclined portion of the plate 38 is provided with two threaded holesin which are revolubly mounted the threaded positioning pins 43extending through the member 19 and having turning means 44 on the rearend thereof. 1

The forward ends of these positioning pins 43 bear against the rear ofthe last 29 on opposite sides of the. center thereof and by properadjustment thereof the work 29 may be tilted to cause the work to bepresented to-the saw in proper position.

The saw machine frame has adjustably mounted thereon the gageplate 45adapted last 29 so thatthe depth of cut therein, when the last ispresented to the saw, may be accurately determined.

By means of these different positioning devices an irregular body suchas a last 29 may be mounted on the member 19 at any desired angle andinclination and rigidly held thereon while being subjected to therapidly rotating saw 11.

In the upper end of the frame 19 is a slot in which is positioned an eye51 of a rearwardly extending threaded rod 52, a pin 53 mounted in theframe 19 extending through said eye 51 and forming a pivot therefor.

The rear end of the rod 52 extends through a slot 54 in the upper end ofa post projecting upwardly from the frame 14.

On opposite sides of the post 55 said rod 52 has adjustably mountedthereon the nuts 56 and 57 said nuts being so positioned on said rodthat when the nuts 57 engage the front of post 55 the rear movement ofthe member 19 is determined as shown in Figs. 1 and 4 of the drawings,while the nuts 56 will determine the forward position of said member asshown in Fig. 5.

In the operation of the machine, the last 29 is located properly on themember 19 when the latter is in the position shown in Fig. 4 with thetoe thereof touching the gage plate 45.

The entire frame 14 with the parts thereon is then moved transversely ofthe sawing machine 10 and as the saw 11 moves through the toe of thelast 29 the saw cut 58 will be made as indicated in Fig. 7 of thedrawings. 1

The frame 14 will then be returned to its normal position and theoperator will grasp the handle 20 and move the member 19 into itsforward :position as in Fig. 5 and the frame 14 will again be movedtransversely of the machine 10 and a second cut will be made in the toeof the last 29' at an acute angle to'the cut 58 leaving the toe of thelast 29 with a \I-shaped notch 59 extending transversely thereof.

The machine is particularly designed for making this V-shaped notch 59in the toes of lasts preparatory to remodelling the same to ive themshapes in accordance with modiern styles. utilizing the bodies of old"lasts or lasts of obsolete styles all as fully described in anotherapplication of mine for lasts and method of making the same and of evendate herewith.
